Greenbrae, California is an unincorporated community in Marin County, California located on the east shore of the San Francisco Bay across from San Francisco and adjacent to the city of San Rafael, California. The neighborhood occupies low coastal hills and shoreline along San Pablo Bay and lies near major regional corridors linking Marin County to the Golden Gate Bridge and the rest of the San Francisco Bay Area. Greenbrae combines residential neighborhoods, commercial strips, and shoreline parks with views of the Mount Tamalpais ridgeline and the Sausalito, California shoreline.

History

European colonization of the area that includes Greenbrae followed Spanish exploration connected to the Portolá expedition and later land grants such as Rancho San Rafael and Rancho Corte Madera del Presidio. In the 19th century, the broader Marin County region saw development tied to California Gold Rush supply routes, timber exports to San Francisco, and agricultural ranching associated with families from the Mexican Rancho era. The 20th century brought suburban development following construction of regional transportation links like the U.S. Route 101 in California corridor and expansion of communities such as San Rafael, California and Larkspur, California. Postwar growth paralleled the rise of the San Francisco Bay Area's residential suburbs and the development of commercial centers near Interstate 580 and other Bay Area freeways. Local planning and land-use debates engaged entities including Marin County Board of Supervisors and regional agencies such as the Metropolitan Transportation Commission.

The area lies within the San Andreas Fault region of northern California tectonics that shaped the Peninsula and North Bay physiography. Climate is classified as Mediterranean, influenced by marine air from the Pacific Ocean and moderated by the Golden Gate Strait; summers are typically dry with cool fog intrusions from the Pacific Ocean, while winters are mild and wetter, reflecting patterns observed across the San Francisco Bay Area and California Mediterranean climate zones.
